L'EQUIP ''FilterPro'' Food Dehydrator, whiteThe L'Equip Filter Pro is basically the same unit as their standard dehydrator, but with HEPA filtration added. The air is going to be circulating around the food for long periods of time and this really helps to keep from picking up ambient odors. If this is to be used in a commercial kitchen, we highly recommend the Filter Pro. In this environment, you are really going to benefit from the internal (washable) filtration system.
